When you consider that a 3.2V lifepo4 cell is considered fully charged at 3.6V and empty at 2.5V the shutoff voltage of 48.1V is protecting the cells and discharging to 44,8V or 44V might give you the full 5Kwh.
86%...The DOD mostly is around 80%...I had a chat with Felicity Engineers. So 86% of capacity is good for use. When one designs a system, a service factor of 1.25 is recommended. 25% of capacity should be left to increase the life of batteries (LiFePO4).
Wow I am very pleased and so impressed that you could go all the way to show this very rear and highly anticipated research for we Nigerians to see!! Thanks alot and I am so subscribed for more updates on felicity lithium batteries!!
I believe in a previous video one of the qr stickers says 276wh right, so thats 86ah. The total capacity would bd 4.41kwh, so it is close enough. Felicity is not honest with their claims. My 300ah tower battery can only do 271ah instead of 300
@@diyfalke Do not know how much you payed for it, i bought 16x CATL FFH3D3 (same cells that are in your Felicity) and paeyd 590€. Add over this a BMS (100€ = 2A active balancing) => 690€.
Try to Charge the battery to its full capacity and drain it fully again so that you can unlock the capacity more as it may have been sitting idle for too long and needs a few circles to unlock its maximum capacity.
My friend.... I have a 24v240Ah lifepo4 battery and im using the same battery monitor. Its not showing the SOC meter for some reason. Its driving me crazy. I've watched all connection instruction videos and everything it correct. The soc meter was working with my 12v lead acid battery 😡
4.3/5.0 x 100%= 86%. Not bad but could have been better. Any reason for not being able to set the highest charging voltage(floating/absorption) to the recommended 57.6v or even to 55.2v? Probably, you could have gotten a higher capacity than the 4.3Ah if you started draining from the higher floating voltage. Well done Sir for the review..
I attempted to charge the pack to 57.6v, but as the voltage hit 57 sometimes jump to even 60v, the charge controller will cut off with an error 04, which means battery voltage too high. Then it will reconnect and attempt to charge to 57.6v again. The only two logical explanation i have are either the MPPT is not good or 57.6v is too high for the packe.
I tried 2 other MPPT (both Felicity) reduce the charging voltage to 56.8, 56.4v, 56v, 55.6v, and even 55.2v, the same thing happened. Until I assume the pack is 15s, and take the Max for cell to 3.65v which gives 54.75v, the battery charge in a typical way, and the soc bar indicates fully charge. So until I open the inside, I think the battery is 15s, and you can only charge 16s to 57.6v i.e 3.6v per cell.
@@diyfalke Being too long at the peak voltage or lower voltage is something the BMS will not allow. Also, it could be the software aspect. We did one installation last year we had error 04 for the 5 kW Inverter (IVEM) and the 170 Ah / 48V at panel voltages higher than 270 V (for 450 V maximum). We reported and were sent a software upgrade for the Inverters. Once we upgraded the software, the error was no longer there. I see it as a good move for the BMS regulation as you can still build charge at the other voltages.
This is a very good job Hamidu. Many thanks for your efforts to let us understand how these batteries are. Can I have your number for consultancy purposes? I will appreciate it. Na Gode.
Im using the 5kw felicity powerwall batt with 2pcs x 1hp inverter acs. 1double doors dual inverter ref and lights and it could last 5 to 5 n half hours. Is it good enough or should it be doing better?
I'm not sure about the ambient temperature in your location, as it relates to you AirCon power consumption, but I think 5hours is really good. In my location, it runs 1.5hp Aircon, TV and some lights for about 4hrs give or take.
Let's say 1hp consumes average of 920w each hour, the actual capacity of the battery is 4400Wh, at 80% DOD, the usable capacity is 3520Wh, this means, when fully charged this battery can safely run 1hp Air-condition for 4 hours. The battery can deliver 2200W continuously (@0.5c) and a surge of 4400W (@1C) for few seconds.
You are recommended to discharge dry cell battery to 50% DOD to get the most cycles out of it, so A 5KWH lithium battery discharge to 80% DOD is equivalent to 3.3NR of 200ah Lead Acid battery discharge to 50% DOD.
800ah because you are taking 50% of dry cell which 400ah is 4kw so to get 4kw you get 800ah dry cell and get 4kw from it ,4kw in the sense that the 5kw is to be taking out 4kw from it
I have not, I'm hoping to get my hand on one soon. How can one tell grade A cells from B? The only information I heard is A+ cells passes all the test required to be used in EV.
I'm sorry you are having difficulty with your setup, however I do not work with Felicity solar, nor in anyway affiliated to them. But i will be more than happy to help you in any way I can.
I have had this for only 10 weeks, so far there no single issue, the main issue many had with Felicity batteries is the overrated capacity. They have another series made for European customers, these could definitely have greater build quality, more accurate capacity rating and probably better BMS due to the low temperature in the winter.
@@caniceonuoha I take it you mean 75KWH battery bank. If so, I will say it depends on the budget and location of use. Compared to other brands like Pylontech, EG4, and BattleBorn etc, Felicity cost a fraction of these brands, the Felicity LPBF series have greater value for money, I will hardly recommend the LPBR series to anyone. The LPBA series are in the same league with EG4 in the price range, amongst the two, I will always go for EG4. Even the Felicity LPBF series have two or more class, one promising >=3000 cycle, the other 6000 Cycle.

I always say it. Felicity Solar are not honest with their battery rating. This is broad day rubbery and they need to be honest. 4.4K rated for 5k is bad.
@@davidniquot6423 I believe if a manufacturer can lie about the capacity, they can be lying about other things, and I only see the datasheet of CATL FFH3DS, which has >=3500 cycle life.
To calculate backup time for 5KWH battery, you first decide the depth of discharge (or usable capacity) say Felicity recommend 80% DOD, which means the usable capacity is 5000Wh * 0.8 = 4000Wh. This means you can run a load of 4000w for an hour. 2. If the load of 550w is including the inverter no load consumption fine, else add the no load power consumption to the load. This can be found in the inverter manual, or you can measure it with clamp meter. 3. Divide the total load(including no load consumption) by the efficiency of the inverter. Assuming 90% efficiency, that is 550w/0.9 = 611w. 4. Divide the usable capacity of the battery by the the load result calcilated in 3 above. That is 4000Wh/611w = 6.55h or 6h 33minutes. Summary. The Felicity 5KWH battery can safely run a load of 550w for 6h33min.
When you consider that a 3.2V lifepo4 cell is considered fully charged at 3.6V and empty at 2.5V the shutoff voltage of 48.1V is protecting the cells and discharging to 44,8V or 44V might give you the full 5Kwh.
